A:AnswerOur World Travel adapter is not a voltage converter. You are able to use devices that are rated for 120/240 volts. Please keep in mind that if your device is rated for 120v and you plug it in to a wall socket that is rated at 240v it may result in damage or injury. Italy's average voltage is 230v. What is the cpap machine voltage rated at? You can contact our customer support team at 877-482-7487 Monday thru Friday 10 AM EST to 7 PM EST. They will be happy to help you.
A:AnswerIt will allow you to plug in and get power, although your straightener might not function exactly the same way due to the current differences. I like how compactly it provides adapters for all different outlets.
A:AnswerI believe Jamaica uses US style plugs per a quick Google search. So it should work to convert non-US plugs. If you are using a US plug no conversion should be necessary.
